Need walkthrough to allow user to enter text, run python code, return result

I’m a python programmer but a neophyte to php and a wysiwyg user of wordpress. I have a problem I need help with. I have a python code called text.py which does some stuff to a line of text. In reality it is some complicated natural-language processing. For now, let’s say it returns input text in all caps. I would like to make a wordpress page that has an input box where the user can enter text, click a button, and that text will be sent to the python code, the results of which will be shown back on that page underneath.

For kicks, here is a sample python code text.py:

`import sys
if __name__ == “__main__”:
print ” “.join(sys.argv[1:]).upper()

>>>python text.py “hello there world”
HELLO THERE WORLD`

Looking around the web, I haven’t found any comprehensive “here is what you do” from start to finish. I think this could be REALLY useful for other people trying to do similar things.

I have python running on my web server, so that part is taken care of. I could use a step by step tutorial of how to:

1. create the page with a box to enter text and a button to run the code.
2. interface to send that text to the python code and run it
3. way to print the output on the wordpress page.
